Edata: Move sn into its own field.
...
This lets the bins use a fragmentation avoidance policy that matches the HPA's
(without affecting the PAC).

Introduce hpdata_t.
...
Using an edata_t both for hugepages and the allocations within those hugepages
was convenient at first, but has outlived its usefulness. Representing
hugepages explicitly, with their own data structure, will make future
development easier.

HPA: Manage whole hugepages at a time.
...
This redesigns the HPA implementation to allow us to manage hugepages all at
once, locally, without relying on a global fallback.

Rename edata_tree_t -> edata_avail_t.
...
This isn't a tree any more, and it mildly irritates me any time I see it.

Add psset: a set of pageslabs.
...
This introduces a new sort of edata_t; a pageslab, and a set to manage them.
This is part of a series of a commits to implement a hugepage allocator; the
pageset will be per-arena, and track small page allocations requests within a
larger extent allocated from a centralized hugepage allocator.

Edata: rename "ranged" bit to "pai".
...
This better represents its intended purpose; the hugepage allocator design
evolved away from needing contiguity of hugepage virtual address space.

Edata: zero stack edatas before initializing.
...
This avoids some UB. No compilers take advantage of it for now, but no sense in
tempting fate.

Edata: Add a ranged bit.

We steal the dumpable bit, which we ended up not needing.

Rename extent_t to edata_t.

This frees us up from the unfortunate extent/extent2 naming collision.

Rename extent.h -> edata.h.
...
This name is slightly pithier; a full-on rename will come shortly.
